SPRING TRUCK-FRAME.

SPECIFICATION forming part of Letters Patent No. 228,781, dated June 15,1880. Application filed December 30, 1879.

To all whom it may concern Be it known that I, JOSEPH ROEMER, ofPortland, in the county of Multnomah, in the State of Oregon, haveinvented an Improved Spring Truck-Frame, of which the following is aspecification.

My invention relates to the application of springs to a truck-bed insuch a way that the springs do not take up much room under the lowtruck-beds in common use, such trucks at present not having springsapplied to them, so far as known, except in a common truck with highaxles.

In Figure l of the drawings is shown a side elevation of the truck, andin Fig. 2 a plan of same.

can are springs; b, the goose-neck; c, a crossbeam, of wood or iron; (I,the truck-bed; e, the hinder axle; and f f, the side beams, of wood oriron, called reaches. These side reaches are bolted to axle e and thegoose-neck b; or the goose-neck may be made in one piece, reaching theaxle.

The cross-beam cis made use of for two purposesone as a stretcherbetween the reaches, and the other as a support to the springs to at thefore part of the truck-bed d, the hinder pair of springs being bolted tothe axle e.

In this arrangement of springs and frame a double purpose is gained, thefirst being the draft of the load by the frame or reaches f, attachedsolidly to the axles, they being so situated under the bed (I that whenthe springs are overloaded the weight shall rest on the frameorreachesf, and not endanger the springs by breakage, the bed carryingthe load being of such a size that it overlies the frame or reaches f atthe sides sufliciently for holding the load when the springs are down incase of overloading.

The inventor is aware that springs have been applied to the hind axlesof trucks in such a way that the wheels are drawn by the springs, thefore part of the bed or body having no springs; but in the device shownthe fore and after parts of .the load rest alike on the springs, and thewheels are drawn by the frame instead of the springs, and the springs,having the single duty of supporting the load, are much less liable toaccidental breakage than in the first case.

This form of truck-frame is believed to be new, embodying, as above, theprinciple of carryin g the springs, and also the truck-bed, whenoverloaded.

There may be three or four of the reaches f attached to the goose-neck,and also two or more of the cross-beams c, in connection with the axlee, for holding more than two pairs of springs for heavy loads.

The springs may be of any of the forms usually used for such purposes.

I claim- A truck-frame, as shown, consisting of the parts a b c d of, incombination, substantially as described, and for the purpose set forth.

JOSEPH ROEMER.

In presence of- F. W. LEWIS, O. B. TALBOT.
